Abstract
An integrated wet-rotor zoning circulator for circulating fluid within a zone in a hydronic heating or cooling system. The zoning circulator has three primary components: a motor, an impeller casing, and a controller. The controller, which is integrated with the motor, houses a voltage transforming device (e.g., a transformer) and a switching device (e.g., a relay). When a thermostat in the zone being served by the zoning circulator closes, the switching device closes and the pump is activated.
